Performed diagnostic on 5 year old unit. Homeowner says unit is not cooling. It is blowing air but it is not cold. Checked outdoor unit electrical and system components. Checked refrigerant pressures and found unit to be low on refrigerant. Performed leak inspection and found leak at outdoor liquid line drier. Line drier needs to be replaced. Unit is also low on refrigerant from leaking and will need refrigerant. Went over findings and recommendations with homeowner as well as the process for replacing liquid line drier and all the steps involved with that process. Homeowner would like to move forward with repair. Collected $169 as down payment, remainder to be collected when we return to perform work. System is not operational upon departure.
